on m prepa f :S9/f.. we mean. to designate any coupling t0- .;etuer @if ih@ pa'cs tha Wll admlt @if the he main section l; of Ehe fm substantaly a5 and fm: ich@ purpose harem set. forth, Thus.,

by-Way of exempcaton in the acc0mpany-- ing" drawings, We show 'Cha paris as' hinged lather by pntets p, p2 passngthmugh the ai ntfaockng kiama-Mes le, is., the bingas "being positioned ajacen; to the inner Side of me rim, so that. he haggle Sectn 9L? may 3, i@ an elevation 0f our (immuni-abi@ -nm cnilapses, he :mm1-mal or expandae p "13a mcum ccnnectima. as herein be depressed inivelrd centrally as. shown in Figs. 3 and 5; It will lbe noted, by reference more particularly to Figs. 4 and 5, that in beither positiori of the toggle the medial pintle 7)', is beyond the line of dead center, z'. e., the plane ,of theshortest line between the pintles p, p, which' secure the toggle `levers 21,A 22, to the main section 1, oi the rim, as indicated by -the-,dotted linesc, in

seid ligures, so that the, resilience of the main seotionlwill tend constantly to main- 'tain the toggle section 2,in either position.

Thus in Figs. 1, 2, 4 and 6, the outer end shoulders 3, 3, of the levers 21, 22, are held '.in contact with the shoulders 11, 11, on the by the dotted lines in said Fig. 3.

Hence is Will be seen that by depressing thetoggle section 2, ofthe rim the latter will be contracted sufficiently in diameter and circumference to admit of its removalv from or insertion within the shoe or tread T, of the wheel, thereby simplifying and facili tating the operation of tire mounting.

The inner sides of the toggle levers 21, 22, ere formed with shoulders 5, 5, for engage'- iekieo ment with corresponding peripherelshoulf ders` f, f, on the Wheel telly, as shown in Figs. 1 and 2, of the drawings, thereby preventing the creeping of the rim circumferentizilly on said i'elly. rlhese shoulders 5-5, on the toggle sections 21-22, acting in consjunction with the corresponding lslioulders f, f, on the telly, forni e distinctive Afeature in our construction and errangemlentiI of i parts, and edd materially tothe effectiveness and utility of our demountnble rirn by locking the toggle sections on the telly by simple means, and Without resort to extraneous clamps or devices of any kind for this purpose. In otherwords, our contrectible and yexpzinsible deinountable rim is seltcontained and unitary in this respect, and comH plete in every particular, not being dependent upon extraneous Ineens of attachment or manipulation. s

What We claim es our invention end desire to secure by Letters Patent is A.' trensplit demounteble iim'comprising a major section having its ends spaced epert and connected by a tivo part inwardly opening toggle, the sections thereof being pivoted together and to the ends of the mejor section, the inner sides of the toggle sections being provided with transversely extending oppositely 'facing shoulders together adapted to act as a driver.
